DETACHABLE CELLAR-SPRAY.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed. November 23, 1907. Serial 110.403,!575.

To all whom it may concern:

Be it known that I, J OHN F. OLIVER, a citizen of the United States, residing at Council Bluffs, in the county of Pottawatta'mie and State of Iowa, have invented certain new and useful Improvements in Detachable Cellar-Sprays, of which the following is a specification.

This invention relates to attachments for the nozzles of fire hose, to provide means for discharging the water in the fornrof laterally projecting sprays, or finely divided particles of water, and has for its object to pro- -or toward the nozzle, while the water at the a claims, and in the drawing is shown the preouter portion of the device is projected in outwardly and forwardly extended finely divided sprays or jets, while the'water will be projected at the central portion of the device substantially at right angles thereto and in relatively large jets, so that the water will be utilized to dispel the smoke in the neighborhood of the'nozzle for the protection of the operator, while the disseminated sprays at the outer end will operate effectually in subduing the fire.

With these and other objects in view, the invention consists in certain novel features of construction, as hereafter shown and described and particularly pointed out in the ferred form of embodiment of the invention, Figure 1 representing the improved device in longitudinal section and applied to an ordinary hose nozzle, the latter being in plan view. Fig; 2 is an elevation of the body portion of the improved device detached. .Fig. '3 is a detached perspective view of the mutilated threaded collar whereby the body portion is coupled to the nozzle, the portion of the device shown in Fig. 3 also illustrating a slight modification in the construction.

ing the operation of the device.

It is frequent y desirable in subduing fires that are inaccessible to the ordinary stream from the hose to project the water in the form of a spray or widely disseminated jets, especially where the fire is in close proximity to a roof or beneath a floor or a similar location, and in operating .devices of this character, an aperture is made in the floor or roof, and the spraying implement inserted, and the Water discharged as before described in the form of widely disseminated sprays or jets, and the improved device herein shown is designed to be employed in connection with the discharge end of an ordinary hose as used by firemen, and consists in a hollow body portion 10, preferably in globular form and with an intake 11 at one side corresponding to the discharge of a hose nozzle, and with an enlarged internally threaded socket 12, the latter adapted to bear over the outer beaded end ortop 13 of an ordinary hose nozzle 14, the socket being considerably larger than the head of the top, as shown in Fig. 1.

Adapted to be passed over the neck portion of the nozzle l'is a securing element consisting of a substantially U-shaped collar 15 externally threaded to engage the threads of the socket 12, when passed over the nozzle and rotated. A packing 16 of rubber, leather, or similar material is inserted between the socket 12 and the top portion 13, as shown.

The member 15 is provided with projections 17 .to receive a spanner wrench or like implement to enable the threaded member to e rotated to cause it to enter the socket, as will be obvious. By this simple means when the improved device is required, the fireman sim ly slips the socket portion 12 over the on of the nozzle, and then passes the member 15 over the neck portion of the nozzle below the socket 12 and rotates it to cause the teeth to engage the teeth of the socket, until the inner end of the member 15 bears against the inner edge of the bead 13, and thus firmly lock the bod portion 10 to the nozzle. This action may e accomplished very quickly, and does not r uire the fireman to disconnect any parts 0 the nozzle, or make other changes n the struclarge apertures 20 bac'kwardlfy' o ture, and when the spray device is no lon r required it can be asreadily detached y simply loosening themember 15 and removin 'it' from the socket. 7

he body 10 is provided with three novel forms ofjet or spray apertures, as shown.

The outer portion-of thebod is provided with a plurality of radially isposed rela tively fine apertures 18, the central portion of the body provided-with relatively coarse or large elongated apertures 19 dislposed substantially at right an les -to the tudinal plane of-the'nozz e, and a plurality of elon ted apertures20 each disposed at an ang e to the longitudinal plane of the nozzle, or the longitudinal lane of the improved attachment.

the water is turned on by manipulating the cut-off 'elementillustrated at 21 in Fig. 1,.

By t is means when it will be projected through the relatively toward the nozzle,. and by the inclined shield ofwater between the fireman and the fire or the origin of the smoke, and effectually eliminate the smoke and protect the fireman,

.- while the water projected through the relazle without alteration t circular wallof water which will efiectually drown out any fire immediately in the vicin-.

material, and of any sizeto ada t it tovariations in the forms andsizes of ose nozzles, and of any required material, but will'preferabl 'be of the same material as the nozzle, whic is usually of. brass or similar com- 7 I pounds. The mutilated collar 15 is formed to" trated in Fig. 1.
